Simer Pumps Condensate Pump 2520ULST - Manual (Page 6)

TROUBLESHOOTING
Pump does not run
• Check power to furnace/AC and to pump circuit. Be
sure pump is plugged in.
• Condensate level in reservoir may not be high enough
to start pump. (Water must be 2" below the top of the
reservoir for pump to start.)
• Dirt or algae clogging reservoir.
• Inlet line clogged.
• Stuck float resulting from dirty reservoir.
• Make sure that float switch is not stuck in the down
(off) position.
Pump runs, no discharge
• Make sure the discharge tubing (especially the end of
the tubing) is not plugged.
• UNPLUG pump and make sure check valve and
impeller discharge port are not plugged.
• Make sure the float switch is not stuck in the on (up)
position.
PREVENTIVE MAINTENANCE
Unplug the pump and clean out the reservoir at the
beginning and end of each heating season. Use a com-
mercial algaecide and follow manufacturer’s instructions.
Putting about a gallon of algaecide solution in the reser-
voir and then cycling the pump several times will keep
the reservoir and the discharge line free of algae build-up.
Be sure to dump the cleaner and rinse the reservoir with
water before starting the pump.
Be sure you do not clog the impeller discharge port or
the check valve when starting the pump after cleaning.
Whenever you replace the motor cover and screws, be
sure that the motor cover catches the float switch pivot
pin and does not pinch either the power cord or the
safety switch leads. Do not over-tighten the screws.
SERVICING A DOUBLE-INSULATED
APPLIANCE
A double insulated product uses two layers of insulation
(one inside the other) to provide protection from electrical
shock hazards. No separate grounding wire is required.
DO NOT try to install a grounding wire on a double-
insulated device.
Only qualified service personnel should attempt to ser-
vice a double-insulated product, because safe servicing
requires extreme care and knowledge of the system. Any
replacement parts installed in a double-insulated product
must be identical to the original parts that they replaced.
A double insulated product is marked with the words
“DOUBLE INSULATION” or “DOUBLE INSULATED”.
